DOOR CLOSING AND FASTENING APPARATUS.

Application led August 21, 1925, Serial No. 51,791, and in France May 6i, 1925.

The present invention relates to an automatic and powerful door closing and fastenin g apparatus, characterized in that it is constituted by a resilient lever arm, rocking about an axis belongingV to one of the parts to be connected. This resilient arm is con stituted by a pivoted barrel which combines, on the one hand, with a resilient push piece placed Within this barrel (the springe,` acting 10 betvveen the said push piece and the bottom of the barrel) and taking' a bearing' o-n the other of the parts to be connected, on the other hand through an outer sliding' sleeve which hooks on the Whole of the system.

The sliding' sleeve therefore, when it is hooked on, holds the system in operative position and the push piece takes a bearing' on the bottom of the barrel for realizing the stress necessary for assembling' the parts to be connected.

'i This system is moreover combined With a locking' mechanism permitting, at Will, to render the sliding sleeve and' the pivoting barrel rigid ivith each other, so as to prevent any fraudulent operation. For that purpose, the sliding' sleeve' carries a lock the bolt of which can receive either a movement of translation, or a movement of translation combined With a rotation, so as'to enter into a staple provided on the rocking' barrel.

In the accompanying' dra-Wing' and by way of example:

Fig. l is a vertical section of the improved closing device in accordance with the features of the present invention, the locking device being` in inoperative position.

Fig'. 2 is a corresponding` vienT thereof, during the actuation of the locking device.

The closing apparatus is essentially consti tuted by a barrel c carrying a side lugpivoted at g between the arms of a fork piece a rigid With one of the parts to be connected. In this barrel cis arranged the resilient push piece c on which acts a spring CZ taking,` a bearing', on the other hand, on the bottom of the barrel 0. Externally to thev barrel c an operating sleeve t can slide which carries at its inner part a heel piece z' capable of enter-V ing into one of the notches?) provided 4on the arms of the fork piece The sliding'sleevefh has aside ,bQSs l the boreof'ivhich is partially scr'eivthreaded Ilfor 'receiving' the outer screiv thread of a bolt mi. This bolt'is provided Vwith driving pins parallel to its aXis of symmetry. These pins tit freely into holes o formed in a Washer p'also arranged in the bore of the boss l. Between the bolt m and this Washer 'p is interposed a springe. The Washer j? has an entrance opening` p1 the depth of which is less than its thickness and a central aperture p2.. In its edge is formed anotch'p3 directed according to a generatrix and in which enters, at rest, a claw r1 lbelonging` to the iiXed plate?n which closes the bore of the boss 1.. rThis plate '1" has also anentrance opening' r2 and a pivotingr dust protector r3. ln inoperative position, the parts occupy the position illustrated in Fig. l.V The bolt m is Withdrawn fromy the staple s carried by the rocking barrel c; the "spring (l pushes back the washer 79 Whichis immobilized in position owing to the engagement of the yclaw r1 in its notch 703. The screw m is prevented from rotating' by the pins" n which enter into the Washer p.

For locking the system, the operating key t is introduced in the entrance openings r2, p1 of the plate r 'and of the `Washer i vFrom this fact, the key-bit t1 pushes back the Washer p and releases its notch p3 from the claw r1. As the Washer p is then free to rotate, it can be actuated by the bit t1 V'of the lrey t. It actuat'es, in itst'urn, through the pins n, the bolt m' which screws in tliescreW threaded part of the boss Z so as to enter into the opening s. vThe rocking barrel c is thus rendered rigid with the sleeve h and the spring d relaxes so as to push back theipushpiece c downwardly. rPhe head of this pushpiece is thus pressed against the member Which is to be held stationary.

For releasing` the member to be held stationary from the action yof the resilient' push piece c, the key t is introduced in the key holes 12--141 of the 'plate r' andl of the Washer p, until, as above described, it isposs'ible to impart to the bolt m a displacementcapable of releasing' it from the opening` 3 ofthe rocking barrel c (position of Fig.'2) By then imparting tol the-Whole 4of `the"`system an angular 'displacement towards the lefthand of the finger, about' the "axis" g aspiv'ot, theheel-piece fis released fronthe 1notch provided "inv the forlrl piece c'. The" sleeve 7i can thenl be d .r'avvnv upwards so as to'` constitute a"lever"al`lowing" toroc'l; towards the ebree-Ci' referee @h Y only and that any other similar means might be used for rendering, at will, the rocking barrel c rigid with the sleeve L which internally slides in the same.
